    High-Performance Memory Challenges

    BY ANN STEFFORA MUTSCHLER

    Designing memories for high-performance applications is becoming far more complex at 7/5nm. There are more factors to consider, more bottlenecks to contend with, and more tradeoffs required to solve them. One of the biggest challenges is the sheer volume of data that needs to be processed for AI, machine learning or deep learning, or even […]

    The Trouble With Models

    BY ED SPERLING

    Models are becoming more difficult to develop, integrate and utilize effectively at 10/7nm and beyond as design complexity, process variation and physical effects add to the number of variables that need to be taken into account.

    Turning Down The Power

    BY JEFF DORSCH

    Chip and system designers are giving greater weight to power issues these days. But will they inevitably hit a wall in accounting for ultra-low-power considerations? Performance, power, and area are the traditional attributes in chip design. Area was originally the main priority, with feature sizes constantly shrinking according to Moore’s Law. Performance was in the […]

    Lots Of Little Knobs For Power

    BY ANN STEFFORA MUTSCHLER

    Dynamic power is becoming a much bigger worry at new nodes as more finFETs are packed on a die and wires shrink to the point where resistance and capacitance become first-order effects. Chipmakers began seeing dynamic power density issues with the first generation of finFETs. While the 3D transistor structures reduced leakage current by providing […]

    Noise Abatement

    BY Brian Bailey

    Noise is a fact of life. Almost everything we do creates noise as a by-product and quite often what is a signal to one party is noise to another. Noise cannot be eliminated. It must be managed. But is noise becoming a larger issue in chips as the technology nodes get smaller and packaging becomes […]

    New Power Concerns At 10/7nm

    BY ANN STEFFORA MUTSCHLER

    As chip sizes and complexity continues to grow exponentially at 7nm and below, managing power is becoming much more difficult. There are a number of factors that come into play at advanced nodes, including more and different types of processors, more chip-package decisions, and more susceptibility to noise of all sorts due to thinner insulation […]

    Multi-Physics Combats Commoditization

    BY BRIAN BAILEY

    The semiconductor industry has benefited greatly from developments around digital circuitry. Circuits have grown in size from a few logic gates in the 1980s to well over 1 billion today. In comparison, analog circuits have increased in size by a factor of 10. The primary reason is that digital logic managed to isolate many of […]

    Minimizing The Risk Of Electromagnetic Crosstalk Failures

    BY MAGDY ABADIR

    Leading semiconductor markets, such automotive, machine learning, large scale computing and networking, are driving the need for high density chips that integrate high performance digital cores with sensitive analog/RF IP, while operating at the lowest power and fastest bandwidth possible. These trends are increasing the sensitivity to electromagnetic (EM) coupling, and requiring designers to worry […]

    Taking Inductance And Electromagnetic Effects More Seriously

    BY Magdy Abadir and Yehea Ismail

    With increasing frequencies, tighter margins, denser integrated circuits, new devices and materials, the necessity of full EM analysis including magnetic/inductive effects is becoming a fundamental question for the industry. Where and when should full EM verification be included? Can some of major chip failures during development be attributed to ignoring magnetic effects? Is the methodology […]

    Is It Time To Take Inductance And Electromagnetic Effects On SoCs Seriously?

    BY MAGDY ABADIR

    Electromagnetic (EM) crosstalk impact on SoC performance has been a topic of discussion for a number of years, but how seriously have designers put EM crosstalk detection and avoidance into their SoC design practice? With increasing demand for faster bandwidth, lower power and higher density electronic systems, isn’t it about time to take inductance and […]

    Preparing For Electromagnetic Crosstalk Challenges

    BY MAGDY ABADIR and Anand Raman

    Electromagnetic (EM) coupling/noise is not a new phenomenon, but increasing bandwidth and decreasing size, along with low-power demands of today’s electronic systems is making EM crosstalk a first order challenge. At clock frequency of 10GHz+ and data rate of 10Gbps+, parasitic inductance and inductive coupling that were previously safe to ignore are no longer. System-on-chip […]

    Mixed-Signal Issues Worse At 10/7nm

    BY ANN STEFFORA MUTSCHLER

    Despite increasingly difficulty in scaling digital logic to 10/7nm, not all designs at the leading edge are digital. In fact, there are mixed-signal components in designs at almost all nodes down to 10/7nm. This may seem surprising because analog scaling has been an issue since about 90nm, but these are not traditional analog components. Analog […]
